Toallwhom it may concern: I

Be it knownthat I, EUGENE L. PERRY, a residing at 170 Cumberland street, in the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Capping- Machines, of which the following is' a specificat-ion. 1

My invention relates to machines for capping vessels such as bottles, jars, and the i 'like, and the object of my invention is to simplify the construction and to make more certain and effective the operation of ma:- chines of this class. I

My machine is specifically designed'for the purpose of applying a jar cap such as shown in the application for patent for jar and bottle closures filed January 5th, 1909, by Edmund Hoffman, No. 470,748, or the same may be used with or without modification for the purpose of applying other styles or forms of jar or bottle caps. 4

My invention'consists in the construction and combination of parts hereinafter 'described and further pointed out in. the claims. In the drawing forming part of this specification: Figure 1 is a side elevation of a machine embodying my improvements showing the plunger head in the depressed position. F 1g. 2 is a front elevation of the same. Fig. 3 is a plan view. F ig. 3 is a sectional and plan view taken on the line w"w Fig. 1, looking in the direction of the arrows.

Similar refer'enoe charactersindicate corresponding parts throughout the several v1ews.-

The machine comprises a suitable frame support for a perpendicularly movable plunger; means for moving the plunger against a spring; means for holding the plunger in a locked posit-ion at the end of its downward movement; a head or chuck rotatable in a horizontal plane upon the end of the plunger; and adjustable means for rotating the head and gripping the bottle pr jar-cap constatement of the main elements of construction of my machine, and I will now proceed .to describe it-in detail.

This constitutes a broad:

the stress of The. particular jar or bottle cap for the I application of which this machine has beendesigned is as follows; The cap shown in Figs. 5, 6, 8 and 9 comprises a crown 1 and 2. The side-flange 2 has inwardly extending lugs or projections 3 struck out on the metal of. the flange. tween these inclined lugs are a series of projections 4 designed for the purpose of allowing the head-turning mechanism to simultaneously grip the cap and turn it.

In Fig. 7 'isshown a jar or bottle 5 haying a neck 6 in which are formed a series of grooves 7 having open entrant portions 8,

lower straight portions 9, terminating'in a contracted terminal 10, the upper wall 11 of the grooves being inclined downwardly toward the inner terminal 10, and the lowerwall 7 inclining inwardly toward the face 12 which is rounded upwardly as at 13. I

In placing the cap on the jar or bottle the inclined lugs 3 are presented to theentrant portions of the grooves. The cap is usually provided with a cork or other suitable lining 14, and the bottle with a sealing rib 15 so that when it is placed on the bottle neck thelugs 3 will not go entirely to the bottom of I Be- I of the neck 6 and having an outer terminal having a slot '40 entering My-machine is .not'only specially adapted for the purpose of applying this particular formof cap or seal to abottle or jar, but 1t is intended that the means for so doing shall embody further means for applying the cap to the bottle or jar by a yielding pressure,

so that the frictional contact between the cap and the jar or bottle may 'be regulated;

' according'to the special requirements in 1;; each case. I. As specifically embodied my inventioncomprises a machine having a base 16 and Can upright shaft 17, a bracket118 com r1s-' ing a barrel 19 through whichthe sha t 17 passes,'bolts 20 for securlng the bracket in variouspositions of adjustment on the shaft,

- .upwardly extending paired arms 21 and a guide-block intermediate webbing 23',

22-connected to the barrel 19 by the bore of the gQ-guid-block 22 being circular to receive a plunger to be described. The base 16 is recessed at '24,

ably located a sheet or block of rubber 25.

' Within the guide-block is adapted to move 25 vertically a rod or plunger 26, the. upper end of which is provided with a head 27 and on a shaft '30 extending between the arni is rotatively mounted an anti-friction 30 roller 31. The lower end 32 of the plunger is'reduced in diameter, and carries the hub 3301? a rotatable head or chuck 34, comprising the hub 33 and an upper-crown 35 and an annular'depending flange 36. That por- .35

' The head 34 comprlses means for-turning it and placing the cap upon the bottle or 1 jar with 'a yielding pressure,

turning means, and returningjboth the head so and said latter means to their origina'lposition. The turning means comprisesa pinch:

' barf41 having a handle 42,- a nose or pro je'ction 43,- and an angular disposed corner 44. The inner face 45 of the pinch-bar nose is conformedon the. same circle as the in-' terior face or cup 46-of the head 34'. The

- i "'fflange 36 is provided with a circumferential and horizontal slot- 47, into which the fore part, including the flange 36, slot 47 and the pinch-'barpiw otally supports thebar. in position for horizontal' movement. The end 49 of the slot.

cap as shown in Figs. 5,

and in this recess is prefer-' 28 forming two side arms 29,

further means W for freeing the cap from contact with the the nose 43, of the pinch-bar so is projected, and' a pin 48 extended through apart so as to allow of an independent turn- .ing movement of the pinch-bar before it comes to bear against the end of the slot I of the head. The inner surface of the nose of the pinch-bar is provided with corrugaably conform to the corrugations or pro ections 4 formed on the pendant flange of the 8 and 9.

The pinch-bar 41 is connected with the frame of the machine, preferably with the barrel 19 by meansofa spring 51 one end of the spring passing over a pin 52,secured to the handle of the pinch-bar; itsother end being secured to stud 53 secured to the barrel 19:. The inner end, of the pinch-bar, specifically its nose, is provided with a bolt 54, having a stem 55 passing through the pinch-bar, a nut 56 and a head 57 on its upper end, which is eccentric to the axis of the stem of the bolt, thenut- 56 permitting the setting of the head 57 in the particular position of adjustment desired. The object of this arrangement is to limit the inward thrust of the nose of the pinch-bar, so that the pressure to be exerted by the'pinch-bar upon the jar or bottle cap may be readily regulated,

the regulation being had by turning the head 57, of the bolt so that'its greater or lesser dimension will be presented betwe'en'its stem and the pendant flange 36 head as shown in Figs. .3 and 6'. In order to. prevent the spring 51 rotating" the plunger-head and the wardly, he hub of the plunger-head is ro-,

strike a lug 59 pendant from the lowerfweb '23 of the bracket 18.

, The means for raising'and lowering the plunger with the head will now be described.

At 60 is a shaft passing through-the arms pinch-bar too' far rearof the plunger I IOU vided with a lug 58 which is adapte to] 2 1, and to this shaft is rigidly secured a cam 61. The cam has two rounded terminal surfaces 62 and 63, the latter being located nearestthe axis of the shaft, the former farthestfrom the axis of the shaft,-and between these two rounded surfaces is an outwardly curved surface forming a shoulder 64. The surface of the cam from the intermediate shoulder 64-;as it approaches the terminal 63 being rapidly inclined as at 65,

the other being slowly inclined as at 66. At 67 is an operating handle fixedly se- .and the spring has raised the plunger'and cured to the'shaft 60 outside of one ofthe arms 21. Surrounding the plunger. 26 above the head 34 into its uppermost position of."

elevation, locked. The handle being moved downwardly, the inclined surface 65- of the cam at which point the parts are 70 t-ions or gripping-surfaces 50 which preferder 64 is reached the plunger will receive its maximum downward thrust. This will bring the plunger head 34; down-uponthe cap- (which has been seated on the bottle or jar neck as before'described) and press it upon the neck-of'the bottle.- VVhen the shoulder 64 passes over 'theroller-the slight incline 66 from it to the maximum plane or'terminal 62 of the cam will slowly of the operating handle,'as shown in Fig; 1"; as does the point 7 O prevent 'furtherupward movement. The spring 68 is then pressing the roller 31 against the cam so that the plunger and the head '34 are held firmly-and in a locked position. In order to prevent the plunger from turning, it is provided that the cam at all stages of its movement,-

works between the two arms at the top'of the plunger. j

The operation is briefly as follows: A jar or bottle is placed upon the flexible bed and .a cap such as previously described with i a cork, waxed paper, or felt lin'in 4 is placed over the neck ofthe bottle the nclined lugs 3 being in line with. the entrant portion of the grooves 7 in the neck of the bottle. The operating handle is then moveddown'wardly so as to force the head 34.- on 'to the cap, pressing the lining down upon the-annular neck 1-5 of the bottle with a force sufficient to make the sealdesired. Asthis may vary, depending upon the character of the goods.

contained in the jaror the bottle, means forregula'ting this pressure, without interfering with the operation of the handle or the full throw or movement of the cam, is provided for by causing the bracket 18 to be adjustably secured to the pillar or shaft 17, as before described. This movement of the head causes the inclined lugs of the cap to occupy their proper position in the bottle grooves,

thedegree to which they are forced down into the grooves depending upon the amount of force which it is'deemed advisable to use in applying the cap. Then the pinch-bar 4:1 is moved toward the operator, the gripping surface 50 on the nose of the pinch-barIfi-rst strikes the corrugations 4 on the flange of the cap with sufiicient friction to enable both neck of the bottle.-

1 between the entrant and their terminals.

the head 3% and the cap to be rotated,;wh'ich forces the inclined edge-71 of the lugs against the inclined wall 11 of the, grooves in the This arrangement per mits the head to be rotated just far enough to bring the cap lugs entirely home or to the end of the groove, or to any distance" portion of the grooves The pressure of the nose of'the pinch-bar is regulated bythe eccentric bolt-head 57 so v that just the exact amount of. pressure de- .-bo t tle', allowing the d pinch-bar to sllde freely over the projections an further press the head 34 down upon 'thecap,the, point 69 ofv the cam acting as the. stop to prevent further downward movement sired will be exerted upon the surface of the 'cap flan e. This will prevent a breaking of the bott e and injury to the surface of the cap. The frictional contact between the nose of the pinch-bar and the flange of the {cap is released when the lugs on the cap have been set in the proper position on the gripping-surface of the on' the cap flange. In'order to insure the completeness of this arrangement, when the at once exert its maximum power to-rotate pinch-bar having on the pin 48 before it will strike the end of the slot., By

the time it strikes the end of the slot its gripping-surface will be entirely free from contact with the cap allowing the head to be lpinch bar is freed, and rotated back, its I blunt corner-44 belng spaced apart from the end 49- of the slot 47, the spring 51 will not rotated back to its original position. By

means of this arrangement the operator is prevented from using his full strength when forcing the pinch-bar against the cap during eitherdirection of rotation of the cap.
